Hey guys,

So i bought a Saffire Pro 24 and was having issues with an express card on my laptop. I think I turned the Pro 24 on and off incorrectly too many times or something and a day later, it won't turn on at all. I know for a fact it isn't the cable. Any ideas if what i did caused that issue, or how to fix it?

Firstly, unplug the d.c. power supply lead from the rear of the Pro24 and then use a voltmeter to check that you are getting volts on the barrel connector at the end of the lead from the external power supply. I don't know what voltage that unit uses, but my guess is that you would see 12V d.c. (centre positive), but it could be anything between 9V and 20V.

If that's OK, and the barrel plug was correctly seated into the d.c. inlet jack on the rear of the Pro24, it looks as though the Pro24 has developed a fault and it's time to return it under waranty. It should happily survive multiple power on/offs, so I wouldn't beat yourself up about having caused the trouble.

To add to Boswell's excellent advice-

You confirmed the cable is good by plugging in a different firewire device into the same firewire port on the same computer using the same cable and the new device worked? If so, you've cleared the cable and computer of any wrong-doing. (pointing the finger at the Saffire)

If not, do that first. Plugging devices in and out of a firewire port while they're powered up (hotpatching) can destroy the little PHY chip - as you'll read in this link.
